Screen blinks / flickers when zooming in and out images or opening videos

[DarkShinobi]

Hi, I have an issue with my laptop. It is a Dell Inspiron 15 7560, OS is Win 10 64.

The screen flickers/blinks black while I am zooming in images, it happens with anything regarding videos as well. I have a screen record of the issue:

So far I have tried to reinstall and also install a different version of each video driver. Both for the Intel HD Graphics 620 and also the Nvidia 940MX, but to no avail.

If I connect a second monitor/screen the issue does not happen on the second one, just with the main laptop screen.

Hello DarkShinobi,

If I connect a second monitor/screen the issue does not happen on the second one, just with the main laptop screen.

Good troubleshooting on your behalf but the outcome suggests that it is a problem with the notebooks screen or video cable I’m afraid.
